Hi guys. I'm looking for a new PSU (my setup: i5-4670k, 8gb ram, 380x). I'm thinking about the CORSAIR RMx Series 750W. Is it worth it? http://www.corsair.com/en/rmx-series-rm750x-750-watt-80-plus-gold-certified-fully-modular-psu-eu

Do you have better recommendation for the same price? I have a tier 4 PSU, so I hope it would be a good upgrade.
What is the difference between the RM and RMx series? I can order both in my country, but I don't see Rm series on corsair's page, only RMx.
Thanks for your answers.
 
Try HWinfo, and see if the results are similar. I've seen significant differences in readings between what's shown as sensor data on HWinfo, HWmonitor, Open hardware monitor, CPU-Z and others. For me, HWinfo has always proven to be the most accurate when re-checked using a volt meter. In some few, rare cases, HWinfo has issues with the sensors on some chipset boards, but usually it's been pretty reliable.
 


It's a good unit, but any decent 520W-550W unit will be more than enough for the system to be quite honest.
 
On Jonnyguru whenever a PSU comes with software for monitoring, they always check it compared to their multimeter readings. At lower loads, the software is usually quite accurate, but it's at the higher loads when the software gets thrown way off. And as Oklahoma Wolf says, the PSU included software, as inaccurate as it already is, is "far better than using monitoring software or BIOS readings" such as HWmonitor, since the software reads it from the motherboard whereas the PSU-included monitoring takes it from a point in the PSU.
 


Hmm the Kingwin Lazer Series comes to mind as something slightly obscure. Though it's out of your wattage range, the NZXT Hale90 is made by Superflower.
 


I have had one in the past. Good units for sure but the fans are loud. . Just want something interesting. Not the G2/GS/XFX/RMx/etc. everyone always buys.
 
I think the XFX Pro XXX may need an adjustment from Tier 1 (opinion). Hear me out. If you read the Jonnyguru review, they find that when there is 1A, 1.5A, and 1.5A drawn respectively from the 12V, 5V, and 3.3V rails (basically super low load on the computer), there is 145mv of ripple on the 5V rail! For some reason, I don't think this should be overlooked. This is, in my eyes, a realistic situation this load. It's not like the crossload where the 3.3V and 5V rails are strained and the 12V delivers barely anything - that's unrealistic today (oh and this PSU has 300mv of ripple on that crossload test!); but this low load is a realistic load and this ripple is terrible.

300mv is the worst ripple I've seen on any unit in my life. Even if it's on crossload, it still has 145mv when the 3 rails are delivering about an amp each. Even if the 12V rail is delivering a few amps, it'll probably still be way out of spec on the 5V rail at like 80mv or something. They even got a second unit from the factory, and it had the same problem!
 


The High Power Astro PT are really high quality and relatively unknown, but it seems they're not in stock anywhere unfortunately. http://www.amazon.com/HighPower-APT-600-Digital-Platinum-HPA-600PT-F14C/dp/B00C983LG6
 


Good luck with that. All the less known/off the beaten path units of any merit that are made by half decent manufacturers are either in regional markets not available here or are expensive, which is why they are less known and considered off the beaten path. All the good units that are affordable, are well known.
 


Totally. And even some really awesome units that are on the market today still, are so expensive. Like the Silversotne Nightjar 520W. One of the highest quality PSUs, fanless, too. This PSU is realistically one of the best power supplies I know of. It has insanely great ripple on the 5V and 3.3V rails, both under 10mv. 12V rail is at 30mv. Voltage regulation is just jaw-dropping. All Japanese capacitors.

It's definitely higher quality than the G2... It's a beast! It's $150, but you do get insanely good quality , as well as fanless, which always comes at a premium. I would buy this over the Seasonic fanless X-Series units.I frankly can't think of power supplies that perform better than this one. Probably outside what TinyVoices wants to spend. If they adjusted the price of this to something like $100, I'd recommend it out the wazoo.
 
I'd not recommend a fanless psu at all. With most case temps starting between 30°C - 35°C after a few minutes of use, and then add a decently warm gpu during some gaming, and thats under 72ish°F air-conditioned room. The insides of that psu have to be reaching higher temps than that. I just can't imagine a scenario where fanless would be of any use. Cpu or gpu, sure, those heatsinks are huge, but those psu's don't seem to have the same or even close ability.
 
I'm looking for a 600-650w unit. I want something obscure that many people don't know about though. Like a Super Flower built Huntkey or similar. Any ideas? Would also like it to be affordable.
Click to expand...

I've seen the Cyonic 650w Gold for around $90. People will tell you it's a crap off-brand. It would be fun.




The Nightjar 520w is a Seasonic unit.
 
The Cyonic 550w unit is available, for 80 bucks. The 650w model doesn't seem to be available much of anywhere in the US. For 80 bucks though, I'd have to say NAY to choosing that over something else just to be different. But maybe it's worth it to you.
 

How about Fractal Design Integra M? It's based on ATNG AG-316, which is an unusual design. Instead of using DC-DC converters like most of the higher end units do, it generates the minor rails with two magnetic amplifiers and regulates the +12V with an LLC resonant converter on the primary side.
It drops down in price every few weeks, so it should be affordable.

Rosewill Valens series can be alright too - there are no tests of them, but it's based on ATNG ATM-G v2 just like this Shaw 650W: http://www.hardwareinsights.com/wp/shaw-psush80pgold850-650w-power-supply-review/2/
Maybe you'd like to play an adventurer and see if Rosewill's units messed something up on the way?

Thermaltake TR2 Gold series could be solid too, except some recent 750W units based on this platform (Sirfa HPM) have some problems: http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=455 - do note that Firepower used Su'scon caps instead of Teapo SC in Thermaltake.

I don't know what "affordable" means to you in particular, but if it's ~$90, definitely take FSP Hydro G: http://pcpartpicker.com/part/fsp-group-power-supply-hg650 - you have probably seen the reviews, it's great.



@anort, these new units come from Seasonic's CES news - there's some more info here: http://www.tomshardware.com/news/seasonic-prime-80-plus-titanium-psu,30861.html
 
I am considering a Rosewill Valens. Whats the verdict on the other Rosewill units? Glacier, ARC (no good I believe), Photon?

The Fractal design looks interesting but at $80 for the 650w, I'll look elsewhere.

I am not going to buy an EVGA or Corsair based on non-PSU related customer support issues. I just do not want to support them.
 
Glacier is completely unknown, while Arc 450-650 units don't have enough tests to determine.
Arc 750 is a different platform than the lower wattage models - it's independently regulated LLC+dual magamp AG-316, just like the Fractal Design Integra M series. But the fan used is unknown (same story with the Valens, actually).

Photon is very good, but uses only a sleeve bearing fan.
